Friday 31st January 2014

Today was quite a busy day and the first thing I got stuck into this morning was the monthly report and once I had this knocked out I then had to do the monthly fire chief report. Somewhere in between I got ARPANSA done and in the afternoon I repaired my manual antenna tuner. I replaced the two germanium diodes that got fried by static electricity during the dry blizzard. I also cleaned up the roller inductor as best I could then took it down to the transmitter building where I tested it and calibrated the forward and reverse power meters. Tonight was fish & chip night and later we watched a Johnny Depp movie called Blow.
